bugs (and fixes) in config process, ATLAS 3.9.4

[Sébastien Kunz-Jacques-2]

while debugging a segfault during config process, I think I found a typo
in CONFIG/src/config.c, lines 177 and 179 : "comp" should be replaced by
"comps". based on surrounding code, I think the error is pretty obvious.
(it triggers a random crash of xconfig when passing --shared to configure)

there is also a minor issue with the configure script itself : starting
line 439, the commands aiming at adding a few lines to lib/Makefile do
not work, because the current dir is not the toplevel build dir when a
full LAPACK lib is built. This results in missing lines in lib/Makefile.
therefore on line 439, one should add :
cd $blddir

Sebastian,

Thanks for this message.  You have indeed found bugs, and have the right
fixes (see below for the bugtracker entries).  The configure bug is
the ugly one, and I guess I didn't see it because I don't use the lapack
tarfile option (I tend to use the -Ss lasrc flag) . . .
